FIG.4

SHUTTING AND OPENING DEVICE, PARTICULARLY FOR DOORS The purpose of this invention is that of embodying a device of the related kind, allowing the conventional hardware associated to the door (locks, handles, keys, etc.) to be dispensed with, without renouncing to the functions of said elements.

Another purpose of the present invention is that of providing a door which together with the opening and shutting members can be embodied with modular structural shapes which are cut at the desired size and mounted in the factory when installed, with evident advantages as far as both the manufacturing cost and the mounting time and the associated labour are concerned.

According to this invention, a shutting device is provided including in combination a panel destined to form the door hinged along a vertical side, a pair of structural shapes or sections extending throughout the height on both sides of the panel near its free edge, and a shutting list, located in the plane of symmetry of the panel, destined either to enter into a groove provided in fixed frame or to be extracted therefrom according to a push towards the plane of the panel, or a pull outwards directed is applied to any points of said sections.

Said handle-like lateral section members are pivoted on end plates located at both cross sides of the panel, and act on said shutting list by a ridge entering into a groove provided in. the list. The ends of the latter are slidingly mounted within slots provided in said two end plates, and against said ends act elastically two springs.

The door-panel is hinged with respect to the stationary frame by means of a pair of sleeve members carried by said panel and located co-axial with the axis of rotation of the door, into said members being introduced two pins carried each by joint base entering in the adjacent upright of the stationary frame.

This invention will be now described with reference to the attached drawings showing by way of non limitative example ne preferred embodiment of the invention itself. I

In the drawings:

FIG. 1 is a partial axonometric view of the unit according to the pre-sent invention, as sectioned by a cross plane;

FIG. 2 shows the detail of the mounting on one of the end plate;

FIG. 3 shows the detail of one of binge couplings;

FIGS. 4, 5 and 6 diagrammatically show the rest on normal position, the opening position and the locking position.

With reference to FIG. 1, the numeral reference 1 denotes a panel destined to form the door. Preferably, the panel 1 can be obtained from a continuous structural shape which will be cut to the necessary size. The stationary frame of the door consists of two vertical uprights 2 and 3, also made of structural shapes provided with an indented seat 4 into which slide the anchoring elements 5 provided with tangs which are embodied in the masonry. In order to serve the function of cover members, are provided the structural shapes 7 snap entering at 8 into the aforesaid uprights. The stationary frame is completedby a cross member (not shown in the figure) connecting the upper ends of the uprights, structurally similar to said uprights.

On both transverse sides of the door-panel 1 (see also FIG. 2 and 3) are mounted the head plates 9 provided with the pins 10 entering into the apertures 11 provided in the panel I. Said plates 9 are also provided with a central pin 12 entering into the hole 13 of the panel 1, and a pair of lateral pins 14 on which are rotatably mounted two handle-like sections 15 and 16, symmetrically located on both sides of the door, near the free edge thereof, and developing throughout the height of the door. Also the structural sections 15 and 16 can be cut at their proper size from a continuous stripe, and are provided with the hole 17 for the pins 14.

Between the two handle-like structural sections 15 and 16, a list 18 is interposed, extending throughout the height of the door, and provided with a pair of grooves 19 on which can act the projecting ridges 20 carried by the handle members 15 and 16. In the list 18 is provided a square hole 21 into which enters the rod 22 carrying at each end a block 23 slidable in the slot 24 obtained in the plate 9. The sliding movement of the blocks 23, and therefore also of the rod 18, rigid therewith, in both directions is elastically opposed by a pair of springs 25 and 26.

As shown in FIG. 1, the fore part of the list 18 can enter into the slit 27 provided in the upright 2. Each of the handles 15 and 16 is provided with a vertical rib 28 projecting towards a corresponding groove 29 provided in the panel 1 and said rib can snap enter into said groove.

For rotating the door a pair of hinge supports is provided, one of which is shown in FIG. 3, Said supports consist of a base member 30 provided with a T shaped extension 31 which slidingly enters into the seat 32 provided in the upright 3. The base member 30 is provided with the pin 33 passing through the slot 34 through the panel 1. The latter is provided with a hole 35 wherein can slide the sleeve 36 provided with the snug 37 located in the slit 34. The mounting is very simple and requires the use of no parti-cular tool; when the door has been located at 90 with respect to the plane of the frame, as shown in FIG. 3, the sleeve 36 is held raised acting on the snug 37 and the pin 33 is introduced into the hole 35 causing it to pass through the slit 34, and then the sleeve 36 is lowered until said sleeve has been completely inserted on the pin 33.

In FIGS. 4, 5 and 6 the various positions of the shutting device have been shown. Beginning from the position of FIG. 4, showing the common position, a pull is applied to one of the handles 15 or 16. The projecting member 20 will engage the groove 19 causing the list 18 to be extracted from the seat 27 and the door is free to move in both directions (FIG. 5).

In order to lock the door from one of its sides (FIG. 6) it will be sufficient to push the handle (for instance the handle 16) towards the panel 1, until the rib 28 will enter into the seat 29 of the panel. By this operation, the list 18 will be entirely pushed into the slit 27 due to the action of the member 38 and against the action of the spring 25 and it is no more possible to open the door by means of the other handle 15 the ridge of which cannot engage the groove 19. In order to release the door, it is sufficient to pull the handle 16 until re- I leasing the rib 28 from the seat 29. Under these condidles at any point, and the double direction of opening of the panel.

The description has been effected with respect to a door, being it obviously understood that the described system lends itself to the embodiment of windows, window-doors, doors of furniture generally and so on.
